The Pilates reformer spring guide provides spring resistance settings for every major reformer exercise. Springs are the primary resistance variable on the reformer — choosing the right combination affects both the challenge level and the correct muscle recruitment pattern.

How to Use the Pilates Reformer Spring Guide
The Pilates reformer uses spring resistance instead of gravity or weights. Springs create a unique resistance that both assists and challenges movement — as the carriage moves away, spring tension increases; as it returns, the tension decreases. This makes spring selection more nuanced than simply adding or removing weight.
Step 1: Select Your Experience Level
Beginners need more spring resistance for stability — the extra tension helps you maintain proper alignment while learning movement patterns. As you develop body awareness and control, reducing springs increases the challenge by requiring more core stabilization. Never reduce springs so much that your form breaks down.
Step 2: Filter by Exercise Category
Use the category filter to focus on specific areas of practice: footwork (leg strength), abdominal/core work, back extension, arm work, or stretches. Each category has different spring requirements based on the muscles being targeted and the movement challenge.
Understanding the Setting Abbreviations
Settings are listed as spring counts and colors: "3R" means 3 red (heavy) springs. "2R + 1B" means 2 red and 1 blue. Some exercises list a range — "2-4R" means start at 4 for beginners and work down to 2 as you progress. Always verify settings with your instructor as body weight and individual strength affect the optimal setting.
Adjusting for Body Weight
The guide shows standard settings for an average body weight (140-165 lbs / 65-75 kg). If you are lighter (under 130 lbs / 60 kg), reduce by one spring. If heavier (over 180 lbs / 82 kg), add one spring to maintain similar relative resistance. The goal is smooth, controlled movement — not maximum resistance.

What do the spring colors mean on a Pilates reformer?
Most reformers use colored springs to indicate resistance. Balanced Body and STOTT reformers typically use: Red = heavy (full spring, ~8-10 lbs), Blue = medium (half spring, ~4-5 lbs), Yellow = light (quarter spring, ~2-3 lbs), Green = extra light. Colors vary by brand — always check your specific reformer's manual.
How many springs should a beginner use on the reformer?
Beginners generally start with 3-4 heavy springs for footwork exercises and 2-3 heavy springs for most other exercises. The extra resistance provides stability and support. As you gain strength and body awareness, progressively reduce springs to increase the balance challenge.
Why do some exercises use lighter springs?
Lighter springs increase the instability challenge — you need more core control to move smoothly. Exercises like leg circles and standing work use 1 spring because the challenge is coordination and balance, not strength. If you feel jerky or cannot control the movement smoothly, add a spring.
What is the difference between Balanced Body and STOTT reformer springs?
Both brands use approximately 8-10 lbs per heavy spring and 4-5 lbs per half-spring. The main difference is the attachment mechanism — Balanced Body uses a loop system while STOTT uses a hook. Spring settings are generally interchangeable between brands at similar resistance.
How do I know if my spring setting is correct?
The right spring setting allows smooth, controlled movement through the full range with appropriate effort. Too much resistance: you cannot complete the full range or your form breaks down. Too little: you cannot control the rebound and the carriage jerks. A good setting creates a slight challenge without compromising alignment.
